The gens Bruttia was an ancient Roman family during the late Republic and into imperial times.
None of the gens obtained any important magistracies until the latter half of the first century AD, when Lucius Bruttius Maximus was proconsul in Cyprus.
The Bruttii were an Oscan people descended from the Lucani, from whom they asserted their independence during the fourth century BC.
This family came from Volceii, in Lucania, and seems to have made a habit of adopting names from the female line.
The combination of Quinctius or Quintius Crispinus probably asserts the family's descent from the ancient patrician house of the Quinctii Crispini.
